While getting out of Taxi at Guangzhou airport, I got a jerk when I lifted my Bag , causing acute pain in my lower backbone. At the time of entrance in Plane I asked the steward and he gave painkillers to me . After some time he came to ask if I was feeling well or not. He offered more tablets that I politely refused to take as I thought it better to consult a Doctor at airport. Similarly when going to Canton from Singapore , at Singapore airport I had taken meal at airport lounge, so when air hostess asked for the food I said I don't need. She brought the menu and asked " Sir whatever you like I can bring for you." On my refusal, she again asked, "Sir, are you sure you don't want anything?" . While going out of plane she said , "Sir, eat something at airport as you have not eaten anything for 4 hours". I really admire the courtesy and hospitality shown by the staff / air hostess of Singapore airline. 100 out of 100.
